a universal horizontal milling machine differs from a plain horizontal milling machine in that it has
a table swivel
the spindle of a horizontal milling machine is on the
column
on a horizontal milling machine the table and saddle are supported by the
knee
a vertical milling attachment is bolted directly to the milling machines
column
the purpose of a vertical milling attachment is to enable you to mount cutters
in a vertical position
a milling machines spindle speed is always expressed in
rpm
cutter speed is the rate at which a particular tooth
passes over the workpiece surface
in order to compute spindle speed you must hace the
all of the above
round shafts to be milled are usually mounted in a
v block
the graduations on the swivel base of a milling machine vise allow you to
Accurately align the workpiece at any angle
a slab milling cutter is designed to make ___ cuts
heavy
a right hand helix means that the
cutter teeth spiral to the right
a left hand cut means that the
feed is fron the left to right
a style B arbor has a
bearing sleeve
a style B arbor is held in the spindle with a
drawbar
you should never tighten the arbor nut unless the arbor support is in position because
the arbor can be sprung
according to the formula sfpm x 4 what wpuld be D the spindle speed in rpm if the cutter speed is 70 sfpm and the cutter diameter is 3 in
93.33
which of the following is not a factor in making a rough cut efficiently
length of workpiece
if you stop the automatic feed before a cut is finished always
stop the cutter rotation
in order to increase surface quality on a finish slab milling cut lower the feed rate and
maintain spindle speed
the first machining step in milling a t slot is to mill
a slot or groove in the workpiece
in a horizontal setup what kind of cutter is used to mill the vertical slot
side mill
to align the cutter exactly over the top of the intended slot you must subtract half the cutter width from the
distance between the slots centerline and the workpiece edge
you can fit a t slot cutter into the horizontal spindle by using a
adapter
